Airtel — prepaid mobile wrong recharge fraud

Address: Hyderabad, Andhra Pradesh, 500044

Website: www.airtel.in/forme/home/needhelp

I recharged my mobile ([protected]) with 399 on oct 4th 2017. But i got 349 package.
What kind of fraud airtel is doing to it's customers. Who took my 50 rs.
Apart from that if i am not eligible for 399 i should fail message.
Airtel either give me 399 package of give back my 399 rs.

Also i complained on this site (http://www.airtel.in/forme/home/needhelp/) two time since oct 4th but they don't even care to give me a reference id nor any customer executive gave call to me.
